Description
The present invention relates to a steel composite beam using a supporting reinforcement frame and a method of constructing a structure using the same. More specifically, the present invention relates to a steel composite beam using a support reinforcement frame that can more effectively secure a section rigidity when a steel composite beam including a steel beam and a lower casing concrete is installed in a column structure, and a method of constructing a structure using the same .

Accordingly, the present invention provides a support reinforcement frame which is formed so as to be able to construct a bottom plate by a deck plate or a precast slab (unidirectional precast slab) by making a steel composite beam more economically and installing it on a column structure And a method of constructing a structure using the same.
According to an aspect of the present invention,
First, an I-shaped steel beam formed of an I-shaped section including an upper flange, an abdomen, and a lower flange is used as the steel composite, and a lower casing concrete is formed to surround the lower flange and the lower abdomen, Inside the lower casing concrete, there is used a material in which a tensile force is introduced by using a tension material extending in the longitudinal direction.
At this time, the end of the I-shaped steel beam is formed to protrude from the both end faces of the lower casing concrete for connection with the pillar structure.
Further, the lower flange of the I-shaped steel beam is formed to be smaller than the width of the upper flange so that the tension member and the inner reinforcement can be easily installed in the lower casing concrete.
At this time, the I-shaped steel beam has a larger width than the width between the upper and lower flanges at both ends protruded from the lower casing concrete, thereby facilitating connection with the column structure and reducing the amount of steel used.
Second, a support reinforcing frame (a channel member and a side plate are assembled in the form of a rectangular frame) is fixedly installed on both side surfaces of the lower casing concrete to form an internal space S between the abdomen portions of the I-shaped steel beam. S) to fill the bottom plate concrete. The support reinforcement frame is used as a support for supporting the deck plate or the precast slab on the upper surface.
At this time, an upper end reinforcing member such as a-shaped steel is used on the upper surface of the support reinforcement frame to prevent breakage or positional change due to the support of the deck plate or the precast slab.
In addition, the supporting reinforcement frame is formed in a rectangular shape so that the deck plate or the precast slab does not have a problem of deformation due to its own weight, and unnecessary reinforcing bars or the like need not be separately installed in the inner space, .
Third, the supporting reinforcement frame is formed to be formed in an inverted U-shaped squared box, but spaced apart in the longitudinal direction of the lower casing concrete. Such a support reinforcement frame can be limitedly installed at both ends of the steel composite beam as necessary, and can be effectively accommodated by the bracing member constituting the support reinforcement frame.
Since the present invention uses a steel composite beam including an I-shaped steel beam and a lower casing concrete into which a tensile force is introduced, it is possible to reduce the height of the cross section between the long and narrow beams. .
In addition, since the steel composite is manufactured by forming the lower casing concrete at the lower part of the I-shaped steel beam, it is possible to minimize the amount of steel used and to freely select the size of the lower casing concrete section. It is easy and economical enough to be secured. This makes it possible to construct a more economical building structure or the like by using the steel composite sheet of the present invention.
Furthermore, it is possible to stably install the support reinforcement frame while controlling the tensile stress generated on the upper casing concrete by installing the support reinforcement frame on the lower casing concrete of the steel composite beam, thereby providing the steel composite box with durability and safety .
